Excess Weight Is Not The Verdict.
For the gold time, researchers have shown that implanting electrodes in the brain's "feeding center" can be safely done - in a beg to bloom a reborn healing option for severely fat people who fail to shed pounds even after weight-loss surgery. In a opening study with three patients, researchers in June 2013 found that they could safely use the therapy, known as preoccupied percipience stimulation (DBS). Over almost three years, none of the patients had any sincere affectation effects, and two even unchaste some weight - but it was temporary medworldplus.com. "The opening thing we needed to do was to see if this is safe," said leading position researcher Dr Donald Whiting, villainy chairman of neurosurgery at Allegheny General Hospital in Pittsburgh.
And "We're at the notion now where it looks have a weakness for it is". The study, reported in the Journal of Neurosurgery and at a encounter this week of the International Neuromodulation Society in Berlin, Germany, was not meant to examine effectiveness neartohealth.com. So the big unconsumed puzzle is, can deep brain stimulation as a matter of fact promote lasting weight loss?
"Nobody should get the picture that this has been shown to be effective," Whiting said. "This is not something you can go require your doctor about". Right now, arcane brain stimulation is sometimes reach-me-down for tough-to-treat cases of Parkinson's disease, a workings disorder that causes tremors, stiff muscles, and authority and coordination problems. A surgeon implants electrodes into particular movement-related areas of the brain, then attaches those electrodes to a neurostimulator placed under the decorticate near the collarbone.
The neurostimulator continually sends little electrical pulses to the brain, which in cast interferes with the oddball activity that causes tremors and other symptoms. What does that have to do with obesity? In theory, Whiting explained, yawning brains stimulation might be able to "override" cognition signaling involved in eating, metabolism or feelings of fullness.
Research in animals has shown that electrical stimulation of a individual acreage of the brain - the lateral hypothalamic zone - can stimulus weight loss even if calorie intake stays the same. The revitalized study marks the pre-eminent time that deep brain stimulation has been tried in that imagination region. And it's an distinguished first step to show that not only could these three inhumanly obese people get through the surgery, but they also seemed to have no vital effects from the brain stimulation, said Dr Casey Halpern, a neurosurgeon at the University of Pennsylvania who was not active in the research.
